Having thus fully described our said invention, what we claim as new and desire to secure byv Letters Patent, is:

1. In a tool for removing battery termi- Y nals, a body, jaws on the body in position to engage under a terminal at opposite sides of a battery post, said jaws being pivoted on the body and having oppositely inclined adjacent faces above their pivots, a tongueiat one side of the body and abutton slidable on the tongue for vertical movement between said pivot pins each extending through a lug and the forks of a jaw, a plunger adapted to bear on a battery post, and a handle engaging said plunger, the relation of the two handles being such that both may be grasped in one hand.

In testimony whereof we aflix oursignatures.

faces whereby said button may lock said jaws I A plunger, substantially as set forth;

- 6. A battery terminal remover having a ment with a battery terminal, a plunger,

means for supporting the plunger in vertical position on a battery post. and a rod-like member on the other handle adapted tobe engaged by said plunger approximately in vertical alinement therewith whereby a blow on said rod-like member is transmitted tot-he post for loosening a terminal;

4. In a tool of the character described, a body having a handle rigid therewith, a pair of:opposed jaws hinged to the body for engagement under a battery terminal, means.

for holding said jaws fixedly in engagement with a terminal, a plunger slidable vertically in the body and adapted to engage a battery post, a handle pivotally connected to the firstnamed handle, an adjusting screw in said pivoted handle positioned to engage said plunger, and a spring for holding the plunger in contact with said screw.

5. A battery terminal remover having a body, a handle on the body with lateral lugs, jaws on the body for engaging under a battery terminal, said jaws having forks straddling the respective lugs adjacent thereto,

pivot pins each extending through a lug and the forks of a jaw, a plunger adapted to bear on a battery post, and a handle engaging sald body, a handle on the body with lateral lugs, jaws on the body for engaging under a battery terminal, said jaws having forks-strad-V dling the respective lugs adjacent thereto,
